RILEM TC 277-LHS report: a review on the mechanisms of setting and hardening of lime-based binding systems

Abstract: The main objective of RILEM TC LHS-277 “Specifications for testing and evaluation of lime-based repair materials for historic Structures” is the revision, adaption and, when necessary proposal, of the test methods to accurately study lime-based binding systems and mixtures, such as mortars and grouts. The empiric use of the lime-based composites and the predominant employ of cement in the field of Civil Engineering have led to the widespread application of test methods developed for cement-based composites to … Show more

“…The mechanical properties of the grouts, measured at 28, 90 and 210 days, are presented in Figure 6. They were gradually enhanced up to 210 days, around 30-250%, with the more intense increase shown in compressive strength and depicting the low strength development rate of lime-based grouts [27,[31][32][33][34].…”

“…In the case of building heritage, grouting is an extensively applied technique for restoring and strengthening historic masonries, as well as for consolidating architectural surfaces [25][26][27][28][29][30][31][32][33][34][35][36][37]. During the past few decades, lime-based grouts have been widely developed, following the principle of compatibility, while multiple grouting systems have been applied, according to the needs of each restoration work [28][29][30][31][32][33][34][35].…”

“…In contrast, for comparatively large cross-sections, a higher degree of saturation may exist near the boundary and lower degree of saturation may exist at the sample core [63]. Under drying, after the moisture in the vicinity of the sample boundary evaporates, the drying front recedes into the material and parts of the pores stop being saturated [64]. Some differential strains occur between the saturated and the less or non-saturated regions, which may cause cracks near the non-drying surface [65].…”

“…Examples of air lime-pozzolan mortars that are more than 2000 years old can be seen in several archaeological sites, both with natural pozzolans [12] and artificial pozzolans [15]. In these modified air lime mortars, it is important to understand the mechanisms of setting and hardening, as well as their chemical and mineralogical compositions [16].…”

“…), and the mortars were just assessed at younger ages. The curing conditions, namely temperature, relative humidity (RH) and salts exposure, should influence the kinetics of the hardening reactions and, subsequently, the mechanical strength [16]. The influence of natural exposure curing has rarely been assessed in previous studies of air lime-Mk mortars.…”
